This is one of those lost jewels of animated television. A show that it's so good that it has to be cancelled. Mybe the explanation for that is the lack of understanding audience that can't value a show made like those early '90 shows, with an incredible absurd and witty humour.
Of course, not to mention that the voices behind the caracters are gold, including Christopher Walken as the depressing and cynic white unicorn.
You really need to see this cartoon, no matter what they say about it.
